Some 2000-odd women are protecting the biosphere in the Gulf of Mannar. The thing to note is that these are backward communities, which is why it's a big deal that women are doing this!
At the farthest end of the Indian peninsula, there is an army of women, who dive into the seas to earn their living. Clad in sarees, their only sophisticated gear they have are the borrowed goggles. They deep-dive into the sea to pluck seaweed that grows on underwater rocks and dead coral reefs adjoining the islands in the Gulf of Mannar.
